Abstract

The system provides reliable testing of the strength of the joint, only destroying those which are not adequate. The system for measuring the clamping strength of a cabling fitting (11) on a cable (10) comprises a test plate (18) which at least one hole in which the cable (10) may be engaged. The cable extends perpendicularly through the hole, with the cabling fitt (11) to one side of the hole, resting against shoulders (20) forming a stop within the recess. The cable is pulled with a given traction force (F), and the shoulders are designed to collapse under a specified force. The success of the fitting in breaking through the collapsible shoulders provides an indication of a successful and strong joint for the cabling fitting.

Description

La présente invention concerne d'une manière générale les accessoires de câblage qu'il est usuel de rapporter à l'une des extrémités d'un câble électrique pour en faciliter l'engagement dans une quelconque borne de connexion aussi bien que pour rendre plus fiable et plus sûre la connexion correspondante.The present invention relates generally to accessories of wiring that is customary to attach to one end of a cable electric to facilitate engagement in any terminal connection as well as to make the connection more reliable and secure corresponding.

Elle vise plus particulièrement, mais non nécessairement exclusivement, le cas où un tel accessoire de câblage, alors plus communément appelé embout de câblage, comporte, d'une part, une partie métallique, en forme de manchon, qui est destinée à être sertie sur l'extrémité, au préalable dénudée, de l'âme conductrice du câble électrique à équiper, et, d'autre part, une partie isolante, en forme de douille, qui, solidaire de la partie métallique, est destinée, elle, à s'engager sur la gaine isolante de ce câble électrique, pour recouvrir l'extrémité de cette dernière et reconstituer ainsi à ce niveau toute l'isolation souhaitable.More specifically, but not necessarily exclusively, it the case where such a wiring accessory, then more commonly called cable end, comprises, on the one hand, a metal part, in the form of sleeve, which is intended to be crimped on the end, previously stripped, of the conductive core of the electric cable to be fitted, and, on the other hand, a part insulating, socket-shaped, which, integral with the metal part, is intended, it, to engage on the insulating sheath of this electric cable, to cover the end of the latter and thus reconstitute at this level all the insulation desirable.

Il importe, bien entendu, que le sertissage de la partie métallique, qui est assuré mécaniquement, à l'aide par exemple d'une pince de sertissage, soit suffisamment ferme pour garantir une fixation efficace de l'ensemble sur le câble électrique.It is of course important that the crimping of the metal part, which is mechanically secured, for example using a crimping tool, or firm enough to guarantee effective attachment of the assembly to the electric cable.

Or, pour satisfaire les dispositions normatives en la matière, il est nécessaire de pouvoir contrôler cette fixation.However, to meet the normative provisions in this area, it is necessary to be able to control this fixation.

A ce jour, ce contrôle, qui, bien entendu, intervient par échantillonnage, se fait en atelier, voire en laboratoire, à l'aide d'une machine de traction spécifique.To date, this control, which, of course, is carried out by sampling, is done in the workshop, even in the laboratory, using a traction machine specific.

Un tel contrôle est donc inévitablement différé par rapport à l'utilisation propre de la pince de sertissage correspondante sur le chantier, et, tout aussi inévitablement, il est relativement coûteux. Such control is therefore inevitably deferred from use clean of the corresponding crimping pliers on site, and just as inevitably, it is relatively expensive.

La présente invention a d'une manière générale pour objet un dispositif de test permettant au contraire d'exécuter sans retard sur le chantier même, et aux moindres frais, le contrôle à assurer.The present invention generally relates to a device test allowing on the contrary to execute without delay on the site itself, and at the lowest cost, the control to be ensured.

Ce dispositif de test, qui est donc destiné au contrôle d'un câble électrique équipé d'un accessoire de câblage à l'une de ses extrémités, est d'une manière générale caractérisé en ce qu'il comporte au moins un trou, qui est propre à un engagement du câble électrique par l'extrémité de celui-ci opposée à celle à laquelle intervient l'accessoire de câblage, et dans lequel interfère latéralement au moins un élément escamotable formant butée pour cet accessoire de câblage et susceptible de céder sous une force de traction donnée.This test device, which is therefore intended for checking a cable electric fitted with a wiring accessory at one end, is generally characterized in that it comprises at least one hole, which is suitable for engagement of the electrical cable by the end thereof opposite to that in which the wiring accessory intervenes, and in which laterally interferes with at least one retractable element forming a stop for this wiring accessory and liable to fail under a tensile force given.

Par exemple, suivant une forme préférée de réalisation, cet élément escamotable s'étend sur une partie au moins du pourtour du trou, et, plus préférentiellement encore, sur la totalité de ce pourtour, en formant alors un oeillet, et il est relié à la paroi latérale du trou par au moins une attache sécable.For example, according to a preferred embodiment, this element retractable extends over at least part of the periphery of the hole, and, more preferentially again, over the entire periphery, then forming a eyelet, and it is connected to the side wall of the hole by at least one fastener breakable.

Quoi qu'il en soit, il suffit, sur le chantier, à l'opérateur qui veut s'assurer du bon fonctionnement de sa pince de sertissage, d'engager dans le trou du dispositif de test à sa disposition un câble électrique équipé d'un accessoire de câblage jusqu'à la butée de cet accessoire de câblage contre l'élément escamotable interférant dans ce trou, et de tirer avec une force suffisante sur ce câble électrique : si l'accessoire de câblage se détache du câble électrique, c'est, à l'évidence, que le sertissage de sa partie métallique sur l'âme conductrice de celui-ci est défectueux ; au contraire, si c'est l'élément escamotable du dispositif de test qui cède, en laissant alors un libre passage au câble électrique à travers le dispositif de test, ce sertissage est satisfaisant.Anyway, all that is needed on site is the operator who wants to ensure the proper functioning of its crimping tool, engage in the hole of the test device at its disposal an electric cable fitted with a wiring accessory up to the stop of this wiring accessory against the retractable element interfering in this hole, and pulling with force sufficient on this electrical cable: if the wiring accessory detaches from the electric cable, it is obviously that the crimping of its metallic part on the conductive core thereof is defective; on the contrary, if it is the retractable element of the test device which gives way, thus leaving a free passage to the electric cable through the test device, this crimping is satisfactory.

En pratique, le dispositif de test suivant l'invention peut avantageusement se présenter sous la forme d'une plaquette, que le ou les trous qu'il comporte traversent transversalement de part en part, et qui peut très simplement et très économiquement être réalisée en matière synthétique. In practice, the test device according to the invention can advantageously be in the form of a plate, that the or the holes which it crosses transversely right through, and which can very simply and very economically be made of synthetic material.

Eu égard à son faible coût, et à la différence des machines de traction usuellement mises en oeuvre, le dispositif de test suivant l'invention est, donc, dans ce cas, un produit consommable à jeter après usage.Considering its low cost, and unlike traction machines usually implemented, the test device according to the invention is, therefore, in this case, a consumable product to be discarded after use.

Préférentiellement, cependant, pour être en mesure d'être utilisé plusieurs fois, le dispositif de test suivant l'invention comporte plusieurs trous, dont chacun est normalement susceptible de satisfaire à une seule et unique utilisation.Preferably, however, to be able to be used several times, the test device according to the invention has several holes, each of which is normally likely to satisfy a single use.

Par exemple, et préférentiellement, ces trous ont alors tous un même diamètre et correspondent tous à une même force de traction.For example, and preferably, these holes then all have the same diameter and all correspond to the same tensile force.

L'opérateur dispose, dans ce cas, et, par exemple, sous forme modulaire, d'un jeu de dispositifs de test différents, dont le ou les trous sont de diamètres différents et correspondent à des forces de traction différentes, en se distinguant alors par exemple les uns des autres par des couleurs différentes.The operator has, in this case, and, for example, in the form modular, of a set of different test devices, the hole (s) of which are of different diameters and correspond to different tensile forces, by distinguishing themselves for example from each other by colors different.

Mais, en variante, un même dispositif de test suivant l'invention peut tout aussi bien comporter par lui-même plusieurs trous de diamètres différents et correspondant à des forces de traction différentes.However, as a variant, the same test device according to the invention can just as well have several holes of different diameters by itself and corresponding to different tensile forces.

Dans tous les cas, par sa forme et son faible encombrement, le dispositif de test suivant l'invention est avantageusement d'un maniement particulièrement aisé.In all cases, by its shape and compactness, the test device according to the invention is advantageously easy to handle particularly easy.

Les caractéristiques et avantages de l'invention ressortiront d'ailleurs de la description qui va suivre, à titre d'exemple, en référence aux dessins schématiques annexés sur lesquels :

  • la figure 8 est une vue en coupe transversale qui, reprise de celle de la figure 3, illustre la mise en oeuvre du dispositif de test suivant l'invention.
    • The characteristics and advantages of the invention will become apparent from the description which follows, by way of example, with reference to the appended schematic drawings in which:
  • Figure 1 is a partial perspective view of an electric cable for controlling which the test device according to the invention is more particularly intended;
  • Figure 2 is, on a different scale, an elevational view of this test device;

  • Figure 8 is a cross-sectional view which, taken from that of Figure 3, illustrates the implementation of the test device according to the invention.

    • Tel qu'illustré sur ces figures, il s'agit, globalement, d'assurer le contrôle d'un câble électrique 10 qui, à l'une de ses extrémités, est équipé d'un accessoire de câblage 11.As illustrated in these figures, it is, overall, to ensure control an electric cable 10 which, at one end, is equipped with a wiring accessory 11.

    Par exemple, et tel que représenté, cet accessoire de câblage 11 est un embout de câblage.For example, and as shown, this wiring accessory 11 is a cable end.

    Il comporte donc, d'une part, une partie métallique 12, qui est en forme de manchon, et par laquelle il est serti sur l'extrémité, au préalable dénudée, de l'âme conductrice 13 du câble électrique 10, et, d'autre part, une partie isolante 14, qui est en forme générale de douille, et par laquelle il est engagé sur la gaine isolante 15 du câble électrique 10, en recouvrant l'extrémité de cette dernière.It therefore comprises, on the one hand, a metal part 12, which is shaped sleeve, and by which it is crimped on the end, previously stripped, of the conductive core 13 of the electric cable 10, and, on the other hand, a part insulator 14, which is in the general form of a socket, and by which it is engaged on the insulating sheath 15 of the electric cable 10, covering the end of the latter.

    Un tel accessoire de câblage 11 étant bien connu par lui-même, et ne relevant pas en propre de la présente invention, il ne sera pas décrit plus en détail ici.Such a wiring accessory 11 being well known in itself, and does not not directly related to the present invention, it will not be described further in detail here.

    Pour le contrôle du câble électrique 10 ainsi équipé de cet accessoire de câblage 11, il est mis en oeuvre, suivant l'invention, un dispositif de test 18 comportant au moins un trou 19, qui est propre à un engagement du câble électrique 10 par l'extrémité de celui-ci opposée à celle à laquelle intervient l'accessoire de câblage 11, et dans lequel interfère, latéralement, suivant des dispositions décrites plus en détail ultérieurement, au moins un élément escamotable 20 formant butée pour cet accessoire de câblage 11 et susceptible de céder sous une force de traction F donnée. For the control of the electric cable 10 thus equipped with this accessory of wiring 11, there is implemented, according to the invention, a test device 18 having at least one hole 19, which is suitable for engaging the cable electric 10 by the end of it opposite to that at which intervenes the wiring accessory 11, and in which interferes, laterally, according to arrangements described in more detail later, at least one element retractable 20 forming a stop for this wiring accessory 11 and likely to fail under a given tensile force F.

    En pratique, le trou 19 a un contour circulaire.In practice, the hole 19 has a circular outline.

    Soit D son diamètre.Let D be its diameter.

    Par construction, ce diamètre D est supérieur au diamètre extérieur D1 de la partie isolante 14 de l'accessoire de câblage 11.By construction, this diameter D is greater than the outside diameter D1 of the insulating part 14 of the wiring accessory 11.

    Il est donc a fortiori supérieur au diamètre extérieur D'1 de la gaine isolante 15 du câble électrique 10.It is therefore a fortiori greater than the outside diameter D'1 of the sheath insulating 15 of the electric cable 10.

    Dans la forme de réalisation représentée, le dispositif de test 18 suivant l'invention se présente sous la forme générale d'une plaquette de contour globalement rectangulaire que le trou 19 qu'il comporte traverse transversalement de part en part suivant son épaisseur.In the embodiment shown, the following test device 18 the invention is in the general form of a contour plate generally rectangular that the hole 19 which it comprises crosses transversely right through according to its thickness.

    En pratique, dans cette forme de réalisation, le dispositif de test 18 suivant l'invention comporte plusieurs trous 19, de même diamètre D et correspondant tous à une même force de traction F.In practice, in this embodiment, the test device 18 according to the invention comprises several holes 19, of the same diameter D and all corresponding to the same tensile force F.

    Plus précisément, dans cette forme de réalisation, tous les trous 19 que comporte le dispositif de test 18 suivant l'invention ont un même diamètre D et ils correspondent tous à une même force de traction F.More specifically, in this embodiment, all the holes 19 that includes the test device 18 according to the invention have the same diameter D and they all correspond to the same tensile force F.

    Par exemple, et tel que représenté, ces trous 19 sont alignés, et ils sont établis à un pas P régulier.For example, and as shown, these holes 19 are aligned, and they are established at a regular step P.

    Dans la forme de réalisation représentée, cinq trous 19 sont ainsi prévus, et leur alignement s'étend sensiblement parallèlement à la plus grande dimension du dispositif de test 18, sensiblement à mi-distance de l'un et l'autre des bords longitudinaux de celui-ci.In the embodiment shown, five holes 19 are thus provided, and their alignment extends substantially parallel to the largest dimension of the test device 18, substantially halfway between one and the other of the longitudinal edges of it.

    Tous les trous 19 étant identiques entre eux, seul sera décrit plus en détail dans ce qui suit l'élément escamotable 20 interférant dans l'un d'eux.All the holes 19 being identical to each other, only one will be described in more detail detail in what follows the retractable element 20 interfering in one of them.

    Dans la forme de réalisation représentée, cet élément escamotable 20 s'étend sur une partie au moins du pourtour du trou 19 dans lequel il interfère, et il est relié à la paroi latérale de ce trou 19 par au moins une attache sécable 22.In the embodiment shown, this retractable element 20 extends over at least part of the periphery of the hole 19 in which it interferes, and it is connected to the side wall of this hole 19 by at least one breakable fastener 22.

    Préférentiellement, et cela est le cas dans la forme de réalisation représentée, cet élément escamotable 20 est un oeillet qui s'étend tout au long du pourtour du trou 19, et seul un tel élément escamotable 20 interfère alors dans ce trou 19.Preferably, and this is the case in the embodiment shown, this retractable element 20 is an eyelet which extends throughout along the periphery of the hole 19, and only such a retractable element 20 interferes then in this hole 19.

    En pratique, l'oeillet formant ainsi l'élément escamotable 20 a un contour circulaire, comme le trou 19, et il est coaxial de ce trou 19.In practice, the eyelet thus forming the retractable element 20 has a circular outline, like hole 19, and it is coaxial with this hole 19.

    Soit D' son diamètre interne.Or of its internal diameter.

    Par construction, il est fait en sorte que ce diamètre D' soit intermédiaire entre le diamètre D'1 de la gaine isolante 15 du câble électrique 10 et le diamètre D1 de la partie isolante 14 de l'accessoire de câblage 11.By construction, it is made so that this diameter D 'is intermediate between the diameter D'1 of the insulating sheath 15 of the electric cable 10 and the diameter D1 of the insulating part 14 of the wiring accessory 11.

    En pratique, l'oeillet formant l'élément escamotable 20 s'étend à distance de la paroi latérale du trou 19, et, pour sa liaison détachable à cette paroi latérale, deux attaches sécables 22 sont prévues, en positions diamétralement opposées l'une par rapport à l'autre.In practice, the eyelet forming the retractable element 20 extends to distance from the side wall of the hole 19, and, for its detachable connection to this side wall, two breakable fasteners 22 are provided, in positions diametrically opposed to each other.

    Chacune de ces attaches sécables 22 s'étend transversalement, et, plus précisément, radialement, par rapport au trou 19.Each of these breakable fasteners 22 extends transversely, and, more precisely, radially, relative to the hole 19.

    Dans la forme de réalisation représentée, le trou 19 est entouré par un tube de guidage 23 sur l'un au moins de ses côtés, et il est en continuité avec la surface interne de ce tube de guidage 23.In the embodiment shown, the hole 19 is surrounded by a guide tube 23 on at least one of its sides, and it is in continuity with the internal surface of this guide tube 23.

    Par exemple, et tel que représenté, le tube de guidage 23 intervient de part et d'autre du trou 19.For example, and as shown, the guide tube 23 intervenes from on either side of hole 19.

    Préférentiellement, et cela est le cas dans la forme de réalisation représentée, le dispositif de test 18 suivant l'invention présente une portion renforcée 24, par laquelle, tel que schématisé en traits interrompus sur la figure 8, il est apte à être saisi entre les mâchoires 25 d'un étau 26 ou d'un quelconque autre organe de maintien de ce genre.Preferably, and this is the case in the embodiment shown, the test device 18 according to the invention has a portion reinforced 24, by which, as shown in dashed lines on the Figure 8, it is adapted to be gripped between the jaws 25 of a vice 26 or a any other such holding device.

    Par exemple, et tel que représenté, cette portion renforcée 24 du dispositif de test 18 forme simplement une portion de plus grande épaisseur de celui-ci.For example, and as shown, this reinforced portion 24 of the test device 18 simply forms a portion of greater thickness of this one.

    Par contraste, la portion restante du dispositif de test 18 forme une portion allégée 27 de moindre épaisseur.In contrast, the remaining portion of the test device 18 forms a reduced portion 27 of lesser thickness.

    Dans la forme de réalisation représentée, cette portion allégée 27 est décalée transversalement par rapport à la portion renforcée 24, et, pour son renfort, elle est bordée, périphériquement, par un rebord 28 dont la tranche est à niveau avec la surface correspondante de la portion renforcée 24.In the embodiment shown, this lightened portion 27 is offset transversely relative to the reinforced portion 24, and, for its reinforcement, it is bordered, peripherally, by a rim 28 whose edge is level with the corresponding surface of the reinforced portion 24.

    En pratique, les trous 19 s'étendent à la frontière entre la portion renforcée 24 et la portion allégée 27, et, d'un côté de ces trous 19, les tubes de guidage 23 s'étendent tout entier dans le volume hors tout délimité par le rebord 28 de la portion allégée 27, tandis que, de l'autre côté, ils font saillie sur cette dernière.In practice, the holes 19 extend to the border between the portion reinforced 24 and the lightened portion 27, and, on one side of these holes 19, the tubes guide 23 extend entirely within the overall volume delimited by the rim 28 of the lightened portion 27, while, on the other side, they protrude on the latter.

    En pratique, également, les tubes de guidage 23 ont sensiblement une même longueur de part et d'autre des trous 19.In practice, too, the guide tubes 23 have substantially a same length on either side of the holes 19.

    Lorsque, comme représenté sur la figure 8, le câble électrique 10 est engagé dans un trou 19 par son extrémité opposée à celle à laquelle intervient l'accessoire de câblage 11, cet accessoire de câblage 11 vient buter, par sa partie isolante 14, et, plus précisément, par la tranche de celle-ci, contre l'élément escamotable 20 interférant dans ce trou 19.When, as shown in FIG. 8, the electric cable 10 is engaged in a hole 19 by its end opposite to that at which intervenes the wiring accessory 11, this wiring accessory 11 abuts, by its insulating part 14, and, more precisely, by the edge thereof, against the retractable element 20 interfering in this hole 19.

    Si, tel que schématisé par une flèche sur la figure 8, une force de traction F suffisante est alors exercée sur le câble électrique 10, soit l'accessoire de câblage 11 se détache de ce câble électrique 10 si son sertissage est défectueux, soit, si ce sertissage est satisfaisant, l'élément escamotable 20 cède, en étant arraché de la paroi latérale du trou 19 au niveau des attaches sécables 22 le reliant à celle-ci.If, as shown by an arrow in Figure 8, a force of sufficient traction F is then exerted on the electric cable 10, ie the wiring accessory 11 detaches from this electrical cable 10 if its crimping is defective, or, if this crimping is satisfactory, the element retractable 20 gives way, being torn from the side wall of the hole 19 at level of the breakable fasteners 22 connecting it to the latter.

    En pratique, le dispositif de test 18 suivant l'invention appartient à un jeu de dispositifs de test 18 différents les uns des autres, les trous 19 de ces dispositifs de test 18, tous identiques entre eux pour un même dispositif de test 18, ayant des diamètres D différents et correspondant à des forces de traction F différentes d'un des dispositifs de test 18 à l'autre, et ces dispositifs de test 18 se distinguant par exemple les uns des autres par des couleurs différentes ou par tout autre moyen de différenciation tel que repère ou autre.In practice, the test device 18 according to the invention belongs to a set of test devices 18 different from each other, the holes 19 of these test devices 18, all identical to each other for the same test device test 18, having different diameters D and corresponding to forces of traction F different from one of the test devices 18 to the other, and these devices test 18 distinguished for example from each other by colors different or by any other means of differentiation such as benchmark or other.

    Bien entendu, la présente invention ne se limite pas à la forme de réalisation décrite et représentée, mais englobe toute variante d'exécution et/ou de mise en oeuvre.Of course, the present invention is not limited to the form of embodiment described and shown, but includes any variant and / or implementation.
